Bionic flapping-wing micro air vehicles (FWMAVs) are promising for a variety of applications because of their flexibility and high mobility. This study reviews the state-of-the-art FWMAVs of various research institutes driven by electrical motor, mechanical transmission structure and "artificial muscle" material and then elaborates on the aerodynamic mechanism of micro-winged birds and insects. Owing to their low mass budget, FWMAVs require actuators with high power density from micrometer to centimeter scales. The selection and design of the mechanical transmission should be considered in parallel with the design of the power electronic interface required to drive it. Finally, power electronic topologies suitable for driving "artificial muscle" materials used in FWMAVs are stated.
仿生扑翼微型飞行器(FWMAV)因其灵活性和高机动性而在各种应用中具有广阔前景。本研究回顾了由电动机、机械传动结构和“人工肌肉”材料驱动的各研究机构的最先进FWMAV,然后阐述了微型有翼鸟类和昆虫的空气动力学机制。由于FWMAV的质量预算较低,因此需要从微米到厘米尺度上具有高功率密度的致动器。机械传动的选择和设计应与驱动它所需的功率电子接口的设计并行考虑。最后,阐述了适用于驱动FWMAV中使用的“人工肌肉”材料的功率电子拓扑结构。
